Abstract

SE PROPONE UN SENSOR PARA DETECTAR GASES QUE FLUYEN A TRAVES DE UNA CONDUCCION DE GAS, EN PARTICULAR GASES DE ESCAPE DE MOTORES DE COMBUSTION INTERNA QUE FLUYEN A TRAVES DE UNA CONDUCCION DE EXHAUSTACION. EL SENSOR DISPONE DE UN ELEMENTO (13) DE MEDICION QUE ESTA HERMETICAMENTE SELLADO EN EL INTERIOR DE UNA CARCASA (11) Y CUYA ZONA (13A) DE CONTACTO CON EL GAS SE PROYECTA FUERA DE LA CARCASA (11) Y ESTA RODEADA MEDIANTE UN TUBO (21) DE PROTECCION DEJANDO UN ESPACIO ENTRE LA ZONA DE CONTACTO DE GAS Y EL TUBO, ESTANDO CONECTADO UN EXTREMO DEL TUBO DE PROTECCION A LA CARCASA (11) Y DISPONIENDO EL TUBO DE UNA O MAS ABERTURAS PARA EL GAS QUE PASA A SU TRAVES. EL SENSOR (10) ESTA DISPUESTO EN LA CONDUCCION (30) DE GAS DE TAL MODO QUE LA ABERTURA (22) DE GAS ESTA LOCALIZADA SOBRE EL LADO (21) DE PROTECCION DE FORMA ENFRENTADA CON RESPECTO AL FLUJO (35) DE GAS QUE LLEGA.A SENSOR IS PROPOSED TO DETECT GASES THAT FLOW THROUGH A GAS PIPE, IN PARTICULAR EXHAUST GAS FROM INTERNAL COMBUSTION ENGINES FLOWING THROUGH A EXHAUST PIPE. THE SENSOR HAS A MEASURING ELEMENT (13) WHICH IS HERMETICALLY SEALED INSIDE A HOUSING (11) AND WHOSE AREA (13A) OF CONTACT WITH GAS IS PROJECTED OUTSIDE THE HOUSING (11) AND IS SURROUNDED BY A TUBE (21) OF PROTECTION LEAVING A SPACE BETWEEN THE GAS CONTACT AREA AND THE TUBE, ONE END OF THE PROTECTION TUBE IS CONNECTED TO THE HOUSING (11) AND ARRANGING THE TUBE OF ONE OR MORE OPENINGS FOR THE GAS PASSING THROUGH IT . THE SENSOR (10) IS ARRANGED IN THE GAS CONDUCTION (30) IN SUCH A WAY THAT THE GAS OPENING (22) IS LOCATED ON THE SIDE (21) OF PROTECTION FACED WITH RESPECT TO THE FLOW (35) OF GAS ARRIVING .
